SOLUTION: Bugs bunny can run nine miles in the same time Elmer Fud can run one mile.If Bugs Bunny runs 15 miles per hour faster than Elmer,how fast can Elmer run?

1.  The condition says that Bugs bunny run 9 times as fast as Elmer Fud:


    x = 9y,                         (1)


    where x is the Bugs bunny' speed and y is the Elmer Fud' speed.



2.  The condition also says that  


    x - y = 15  miles per hour.     (2)



3.  From (1)  and  (2) you have


    9y - y = 15,   or

    8y = 15,   which gives you the solution

    y =   miles per hour  is the Elmer Fud' speed.


4.  Then  x = 9y =  =  miles per hour is the Bugs bunny' speed.



Answer.  The Elmer Fud' speed is    miles per hour.
